(o1. 20e-ss) This invention relatesto carding devices for artificial `teethand more particularly to `an improved construction of a display mount for such teeth upon Which the sametmay be displayed `to best advantage. t l f l` Among the principal objects of the present invention is to provide a `display mount which is exceedingly simple and inexpensive in `constructionyand which ist particularly adapted to receive and retainiirmly` in position most, if not all, of the various types of pinless artificial teeth. Heretofore and prior to the present invention, artificial teeth have been mounted upon display cards either by embedding them in a foundation 4 of Wax supported by the card or by securing them to the card by fine Wire thread or the like laced through the teeth and the card. The use ofthis wire as the supporting medium for 'the teeth has been `generally employed in the case of the so-called pinless teeth, the latter being provided with perforations through which the supporting wire is threaded for securing the same to the card. Usually, a single'length of secur- A ing wire is employed to `fasten an entire row or even several rows of teeth to the card, thus rendering it impracticable to readily remove a single tooth from the card as desired. Not only is this scheme of wiring the pinless teeth to the card rather impractical and quite inconvenient to the person who is required to remove one or more teeth from the card, but it is also relatively expensive and time-consuming from the standpoint of the manufacturer. Accordingly, it is an object of the present invention to obviate these diculties by providinga display card having means thereon for adequately securing the pinless type teeth removably in position without the use of retaining Wires and so eliminating the necessity of providing the teeth with wirereceiving perforations.

A further object is to providej a, card mount for artificial teeth wherein the use of wax, which readily softens and becomes sticky in warm temperatures, is dispensed with as a bedding for the tooth and instead an adhesive surface is provided which is less subject to temperature variations and so insures adequate adhesion of the tooth upon the mount under all climatic conditions.

Stillother objects and advantages of the invention will appear more`ful1y hereinafter,` `it being understood that the present invention consists substantially in the combination, construction, location and relative arrangement of parts,

drawing andas finallypointed outin the ap`` `pended claim. l t

1 In the `accompanying drawing, which isillus` trative of certain preferredembodiments `of the present invention, Figure 1 is a plan view showing a, set of` artificial teethdisposed upon a display mount constructed in accordance with ,and embodying `the principles of the present invention; Figure 12 is a sectionalview taken on theL line 2-2.of Figure.1;p` n L :"Figure 3.is a sectional view taken on the line 3-3of Figure 1; Y l

Figure 14 is a plan view of a somewhat modified construction `of the `display mount enlarged in size to accommodate a double row of artificial teeth;\`` f Figure 5 is a sectionalview taken on the line 5-5 of Figure 4; and Y l. f Figure 6 isa sectional view taken on the line 6`6 ofFigure 4. l

Referringnow to the drawing and more particularly to` Figures; 1 to` Sthereof, it will be observed that the` mount` I0 generally consists of alsubstantiallyflatbase member II, the central portion of which is cut out to provide an open` ing I2 therein of generally rectangular shape. This base member II may be'formed of any suitable material having the requisite strength and stiffness to enable it to be freely handled, a preferred material being cardboard because of its low cost and the ease with which it may be cut or stamped into shape, although other materials, such as sheet metal, compositions and the like, also may well be employed.

Secured to the under-surface of the base member II is a backing ofv adhesive tape I3, this backing being preferably of a size and shape corresponding to the size and shape of the cut-out member I-I so that upon assembly of the two` parts they form in effect a laminated structure as shown in Figures 2 and 3. The adhesive tape I3 is applied to thebase member II with its adhesive coating in contact with the under surface of the base member, the central portion I4 of the adhesive coating being exposed in the region of the opening I2 cut out of the base member II. Thus, the adhesive coating serves not only to bind or cement the base II and tape I3 together, butalso provides. an exposed adhesive surface I4 for securing the teeth I5 in position as shown. The adhesive tape employed may be any `of the many types at present commercially available, although the type which has been found most preferable is the fabric-backed all as described hereinafter, as shown in the adhesive tape SuGh aSiS generally used fOr bandsurface of which istreated with an adhesive coating having the characteristic of remaining tacky for an indefinite period.

As will appear from the foregoing, in the display mount of the kpresent invention, the adhesive or tacky area thereof is confined within the opening I2 of the member Il, the margin of the mount surrounding this area being of such ample proportions as not only to provide adequate Ispace for noting thereon the mold and shade indicia and type of tooth displayed on 'the mount, but also to permit easy handling of the card for the purpose of removing or replacing a tooth as desired. Due to the fact that the portion of the tape which extends across the opening 12in the mount has a certain amount of give, the adhesive surface thereof, when the tooth is pressed thereon, conforms to the contour .of the surfaceof 'the tooth in contact therewith and thus insures .ai'irm `.retention .of thejtooth in position upon `the mount. y y n By .employing a member ft2 of some vdegreeaof thickness, .apronounced marginal edge or shoulder Lm-'ay be provided .about the centralV adhesive area to `:thereby provide, `when the yteeth are pressed into position as shown inFigures 1 and 2, an effect .as thou-gh the :teeth 'were embedded .in the mount.y v It will .be understood, of course, that the size of the mount may be varied as ldesired to accome modate one or 'more rows of .teeth and it is within the purview ofthis invention to construct the base member with a plurality of spaced adhesive zones or areas for respectively vaccommodating different sets `of artificial 'teeth Aswan exampleL lof one such modified construction, reference is In this modied construction the adhesive area may be formed in the manner hereinbefore described by providing the base member with a central opening and then applying adhesive tape I9 of suitable Width `to the under surface so as.

" curement to the under-surface of the member I5 .as vat .2D-'20. In such case, the intermediate portion 2l of the tape rests upon the upper surface of the member I6 with its adhesive coating uppermost and exposed for securement of the teeth thereto. 'In order to provide the portion 21 of the tape with suflicient give to conform it to the varying surfaces of the teeth 'when the latter are pressed into contact therewith, a resilient cushion o-r lining ,22 of felt, rubber or other such material, .may be interposed .between the .base member vIfI and the adhesive tape 1.9.

It will =be understood that the ipresent invention is susceptible of changes and mndiflcations which :may be made from time to time without departing from the :general principles or .real spirit of the present `invention :and it is accordingly intended to yclaim the same'broadly., as Well as specifically, vas indicated 'by claim.

What .is claimed as new and useful is:

*the appended A display .mount for artificial teeth comprisy' ing a supporting member of relatively stiff ma teri'al and Aa strip rof .adhesive tape :secured thereto with its adhesive 4coating exposed throughout a limited area, and cushioning .means .interposed between the ysupperting member 'and .the tape to. provi-dethelatter with a yielding surface which vis .locally conforma-ble to the contour of the tooth surface pressed .into contact therewith.
